1. The combination with an ingot mold having a beveled edge, of a feederhaving a plan view of an octagon corresponding beveled lower edgearranged so that ,a feeder of considerable less or greater diameter willseat itself on the mold and be. retained therein.

2. The combination with an ingot mold having its upper edge beveled, ofa feeder eled and corresponding with the bevel of the mold and arrangedso that the inner walls of the feeder and mold are flush.

4:. An ingot mold comprising a body portion having abeveled upper edgeadapted to center and retain a feeder of different diameters. v

5. A feeder foringot molds comprising a body portion of refractorymaterial having a beveled lower edge adapted to center and retain itselfon molds of different diameters.

6. The combination with an ingot mold havin its upper edges beveledinwardly of a fee er having its lower edge beveled inwardly andcorresponding with the bevel of the mold.

7 The combination with an ingot mold having its upper edge beveled, of afeeder having its lower edge beveled inwardly and corresponding with thebevel of the mold and arranged so that the inner walls of the feeder andmold are flush.

8. The combination with an lngot mold having its upper edge beveled, ofa feeder havin its lower edge beveled and correspon ing-with the bevelof the mold and arranged so that molds and feeders of relative differentsizes can be used and the feeder center itself on the moldand'retainedthereon by the bevel.
